Grigor Dimitrov and Tommy Paul are trying to catch up in the ATP Race to Turin this week. But the story of the event at the ATP Stockholm Open has undeniably been Stan Wawrinka, who is into his first semifinal in well over a year.

Tommy Paul won his career-best 42nd singles match on tour this season, as the fourth seed defeated Laslo Djere 6-2, 7-6 (2) on Wednesday at the BNP Paribas Nordic Open in Stockholm.
